DevOps and Docker Talk

Docker launched "Docker Model Runner" to run LLMs through llama.cpp with a single "docker model" command. In this episode Bret details examples and some useful use cases for using this way to run LLMs. He breaks down the internals. How it works, when you should use it or not use it; and, how to get started using Open WebUI for a private ChatGPT-like experience.★Topics★Model Runner DocsHub ModelsOCI ArtifactsOpen WebUIMy Open WebUI Compose fileCreators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host (00:00) - Intro (00:46) - Model Runner Elevator Pitch (01:28) - Enabling Docker Model Runner (04:28) - Self Promotion!

The Docker Bake Build tool just went general availability, and I'm excited about what this means for creating reproducible builds and automation that can run anywhere  CI locally. I love it. Really, and in this video I'm gonna break down some of the features, the benefits and walk through some examples.In this episode I explain why docker buildx bake exists, what it can do, and I walk through multiple examples of Bake files and how it's better than docker build image and docker compose build. I also touch on BuildKit and Docker's GitHub Actions.There's also a video version of this show on YouTube.★Get started with Docker Bake★Walkthough https://docs.docker.com/guides/bake/ Docs: https://docs.docker.com/build/bake/GA Announcement: https://www.docker.com/blog/ga-launch-docker-bake/Creators & Guests Beth Fisher - Producer Bret Fisher - Host (00:00) - Intro (00:04) - / (00:41) - History Lesson (01:29) - Bake Today (02:43) - Ad for...

Bret and Nirmal reunite for their traditional annual Holiday Special episode of breaking down the most significant developments in cloud native from 2024 and sharing predictions for 2025.

Or watch the video version on YouTube. Bret is joined by Willem Delbare and Roeland Delrue to discuss Aikido, a security tool consolidation platform designed specifically for smaller teams and solo DevOps practitioners. The discussion explores how Aikido addresses the growing challenges of software supply chain security by bringing together various security tools - from CVE scanning to cloud API analysis - under a single, manageable portal. Unlike enterprise-focused solutions, Aikido targets the needs of smaller teams and individual DevOps engineers who often juggle multiple responsibilities. During the episode, they demonstrate Aikido's capabilities using Bret's sample GitHub organization, and show how teams can implement comprehensive security measures without managing multiple separate tools.Be sure to check out video version of the complete show for demos, from our December 5, 2024 YouTube Live stream.★Topics★Aikido websiteAikido on BlueskyAikido on LinkedInCreators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Willem Delbare - Guest Roeland Delrue - Guest (00:00) - Intro (06:20) - Aikido Origin Story (10:32) - What Does AutoFix Mean?

Bret is joined by Mumshad Mannambeth and Vijin Palazhi of KodeKloud for Q&A on what we should be studying and certifying for in 2025. 

Bret and Nirmal recorded this special offline episode at KubeCon North America in Salt Lake City. We hung out at the AWS booth to break down the major trends and developments from the conference. The event drew a record-breaking 10,000 attendees, with roughly half being first-timers to the Cloud Native ecosystem. Starting with Cloud Native Rejekts and moving through the pre-conference events, we noticed Platform Engineering emerged as the dominant theme, with its dedicated conference track drawing standing-room-only crowds.The main conference showcased a notable surge in new vendors, particularly in AI and security sectors, representing about a quarter of all exhibitors. We dissect the key engineering trends, ongoing challenges in Cloud Native adoption, and insights gathered from various conferences including ArgoCon, BackstageCon, and Wasm Day. In our 40-minute discussion, we tried to capture the essence of what made this year's KubeCon significant. It's a great listen whether you couldn't attend or if you're a veteran of the CloudNative community.Creators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Nirmal Mehta - Host (00:00) - Intro (03:38) - KubeCon Rejekts (04:50) - Better Than Namespaces (07:17) - Day 0 (08:32) - BackstageCon and Platform Interfaces (12:35) - Argo CD and Deployment Dashboards (13:57) - GitOps Bridge: Bridging Infrastructure and GitOps (14:49) - Kubernetes Resource Orchestrator (KRO) (16:23) - Fleet Management in Kubernetes (18:12) - Ford's Approach to Kubernetes Tooling (19:36) - CNOE: Community-Driven Kubernetes Reference Architectures (26:21) - AI Integration in Kubernetes Tools (34:03) - Managing Infrastructure at Scale with Karpenter (35:13) - KubeCon Highlights and Future Trends You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.com

Bret and Nirmal Mehta are joined by Ken Collins to dig into using AI for more than coding, and if we can build an AI assistant that knows us.They touch on a lot of tools and platforms. "We're bit all over the place on this one, from talking about AI features in our favorite note taking apps like Notion, to my journey of making an open AI assistant with all of my Q&A from my courses, thousands of questions and answers, to coding agents and more."

Bret and Nirmal are joined by Continue.dev co-founder, Nate Sesti, to walk through an open source replacement for GitHub Copilot.Continue lets you use a set of open source and closed source LLMs in JetBrains and VSCode IDEs for adding AI to your coding workflow without leaving the editor. You've probably heard about GitHub Copilot and other AI code assistants. The Continue team has created a completely open source solution as an alternative, or maybe a superset of these existing tools, because along with it being open source, it's also very configurable and allows you to choose multiple models to help you with code completion and chatbots in VSCode, JetBrains, and more are coming soon. So this show builds on our recent Ollama show. Continue uses Ollama in the background to run a local LLM for you, if that's what you want to Continue to do for you, rather than internet LLM models.

Bret and Nirmal are joined by Michael Fischer of AWS to discuss why we should use Graviton, their arm64 compute with AWS-designed CPUs.Graviton is AWS' term for their custom ARM-based EC2 instances. We now have all major clouds offering an ARM-based option for their server instances, but AWS was first, way back in 2018. Fast forward 6 years and AWS is releasing their 4th generation Graviton instances, and they deliver all the CPU, networking, memory and storage performance that you'd expect from their x86 instances and beyond.I'm a big fan of ARM-based servers and the price points that AWS gives us. They have been my default EC2 instance type for years now, and I recommend it for all projects I'm working on with companies.We get into the history of Graviton, how easy it is to build and deploy containers and Kubernetes clusters that have Graviton and even two different platform types in the same cluster. We also cover how to build multi-platform images using Docker BuildKit.Be sure to check out the live recording of the complete show from May 9, 2024 on YouTube (Ep. 265).

Bret and Nirmal are joined by Neil Cresswell and Steven Kang from Portainer to look at K2D, a new project that enables us to leverage Kubernetes tooling to manage Docker containers on tiny devices at the far edge.K2D stands for Kubernetes to Docker, which is a bit of a crazy idea -- it's a partial Kubernetes API running on top of Docker Engine without needing a full Kubernetes control plane. If you work with very small devices, including older Raspberry PIs, 32-bit machines, maybe industry sensors and the infrastructure we now call 'edge', the container hardware is often hard for you to make simple, reliable, and automated all at the same time. So this project uses less resources than a single node K3S and still allows you to use Kubernetes tools to deploy and manage your containers, which are in fact just running on a Docker Engine with no full-fledged Kubernetes distribution going on there.We get into far more detail on the architecture, the Portainer team's motivations for this new open source project and what its limitations are, because it's not real Kubernetes, so it can't do everything.Be sure to check out the live recording of the complete show from March 28, 2024 on YouTube (Ep. 260).

Bret and Nirmal are joined by Phil Estes of AWS to show us the Finch project, which bundles the best open source tools for building and running containers locally. Now it runs on macOS and Windows WSL2.We've been talking with Phil about this show for months, and now that Finch has come to Windows, we thought it was the best time to clue you in as to why AWS created the Finch project and what it does. You're probably heard of containerd, the most popular container runtime on the planet and BuildKit, the best way, in my opinion, to build container images. Those two work hand in hand in Docker and many other container tools. But you might not have heard of nerdctl or Lima, which are also open source tools that work with containerd and BuildKit to help you run containers locally in a virtual machine. Well, AWS had the idea of making an easy installer for these four tools. That's how Finch was born. Finch is not meant to be a replacement of your existing way to run containers. The tools it installs are a bit of a minimum feature set, if you will, and more focused on providing people the exact tools AWS uses in its container platforms, mainly containerd and BuildKit, which are everywhere in AWS. Rather than building something that's feature equivalent to other local container solutions like Docker Desktop and Rancher Desktop, Finch keeps it simple and does the bare minimum.  If you just want an easily installable and minimal way to build and run local containers at the command line with no goofy, high-end fancy features, pure open source and just on Mac and Windows, at least at this point, you should give Finch a try.Be sure to check out the live recording of the complete show from February 22, 2024 on YouTube (Ep. 255).★Topics★Finch WebsiteBret's local container runtime spreadsheetCreators & Guests Phil Estes - Guest Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Nirmal Mehta - Host (00:00) - Intro (00:35) - What is Finch?

Bret is joined by Neil Cresswell, CEO and co-founder of Portainer, to show us new features in Portainer and how it can manage, deploy, and orchestrate all your container workloads from a single Docker Engine, all the way to multi-cluster and IoT Kubernetes deployments.Portainer is much more comprehensive than you might think. Docker on the Edge, Podman, Kubernetes, in the cloud, in hybrid, you name it; it seems that Portainer supports it. In the show, we also get some updates on new things that have happened in the last couple of years, including adding GitOps support to Portainer, the ability to deploy Kubernetes nodes, and infrastructure.Be sure to check out the live recording of the complete show with demos from February 29, 2024 on YouTube (Ep. 256).★Topics★Portainer Website Portainer on YouTubePortainer on XPortainer on LinkedInPortainer Demo: Kubernetes the "easy" wayCreators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Neil Cresswell - Guest (00:00) - Intro (02:50) - How Portainer Started (05:38) - Portainer's Strongest Use Cases (08:56) - Portainer's Cluster Provisioning (12:42) - Docker Desktop and Portainer (15:22) - GitOps with Portainer (18:43) - K2D Teaser (21:34) - Portainer Across Different Environment Types (25:21) - Portainer's Focus on IoT and Edge (29:01) - Portainer's Evolution and Future Developments (35:03) - Passwords and Secrets Capabilities in Portainer (40:15) - AI Capabilities in Portainer (42:06) - Portainer Editions, Licenses and Pricing (43:09) - Using Traefik for Ingress (44:53) - What's Next for Portainer?

Bret and Nirmal are joined by Ivan Burazin and Chad Metcalf to debut Daytona, an open source "codespaces equivalent."Daytona is a development environment manager designed to automate all the tedious steps a developer needs to perform to set up their development environment. "Essentially, it transforms any machine into a codespaces equivalent."Where Daytona is actually starting in the enterprise is focusing on large dev environment solutions and management of those, and then trickling down to individual developers. So there are two very similar solutions to a problem of many developers and their varying ways that they set up their environments for development, but they're coming at it from two ends of the spectrum.

Bret is joined by Matan Mishan & Roy Razon of Livecycle to discuss developer platforms and how to improve developer collaboration and speeding up feedback and previews.We talk about the various delays encountered in pull requests due to feedback processes, and how Lifecycle's tools aim to shorten this feedback loop in Docker Desktop, local CLI with Preevy, and automated CI workflows. I like how Lifecycle provides multiple locations and ways to get access to people in the preview environments that really lets you just fit the different parts of the tool into your workflow, as opposed to one way to do everything. It's great for getting feedback quickly during the PR process, rather than making people set up their own environments to test their changes. I also liked their ideas around how the feedback loops can be improved.This episode contains great demos so be sure to also check out the live recording of the complete show from December 21, 2023 on YouTube (Ep. #246). ★Topics★Livecycle's WebsitePreevy RepositoryLivecycle Docker ExtensionCreators & Guests Bret Fisher - Host Matan Mishan - Guest Roy Razon - Guest Beth Fisher - Producer Cristi Cotovan - Editor (00:00) - Intro (01:57) - Internal Developer Platform: a self-service solution (06:38) - Lifecycle and the Docker Extension (24:10) - Using GitHub Environments (27:46) - First Steps and What's Next You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.com

Bret and Nirmal are joined by Michael Irwin, DevRel at Docker, to talk about all the products and features Docker shipped in 2023, and what's coming in early 2024. Michael has been on this show many times as a Docker Captain and now as a Docker employee, and it's always great to dig into the details of the products with someone who's been using them for so many years as an end-user and now staff at Docker.

Bret is joined by Alex Kretzschmar to talk about Tailscale, a universal VPN that connects teams, devices, and development environments for easy access to remote resources.Alex and I talk about projects he's worked on in containers over the years and then we quickly get into Tailscale and talking about why he joined the team there. Tailscale is one of those tools that's hard to put down. I've used it for years to connect my personal devices to my home server lab when I'm traveling or servers I might have on the internet that I run temporarily. It connects them all together in a seamless VPN. The product itself comes up a lot in our Discord server when people are talking about needing some secure remote access to something anywhere in the world. Tailscale keeps adding more and more features, I can't really keep up, so we had Alex on the show to talk about all the new stuff, including a client for Apple TV, which at first, I didn't quite understand why, but now it totally makes sense; and a Kubernetes operator that does some slick things around connecting engineers on their local machines to clusters. I found Alex at the Tailscale booth at KubeCon this year and invited him on the show to talk about this relatively new yet ubiquitous-feeling product.  The live recording of the complete show from November 30, 2023 is on YouTube (Ep. #243)★Topics★Tailscale websiteHeadscale websiteTailscale CommunityTailscale Docker Mod Blog PostID Headers DemoDevrel DemoCreators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Alex Kretzschmar - Guest (00:00) - Tailscale Everything (19:37) - Tailscale Licensing (28:24) - Tailscale vs Other Networking Products (32:33) - Server and Key Exchange (33:50) - Does Tailscale Support 'Trunking'?

Application delivery doesn't have to suck. Bret and Nirmal are joined by Solomon Hykes, the founder or Docker, to talk about Dagger and their application delivery-as-code that runs anywhere.

The OCI specifications for registry and image are getting a minor version number update to 1.1 soon, and this could be a big deal for anyone storing artifacts other than images somewhere in their infrastructure. This episode digs into the problem with artifacts today, and how the OCI and CNCF are planning to fix it with the "one registry to serve them all (artifacts)" in 2023/2024.

Bret is joined by Nirmal and a host of friends from the floor of KubeCon, to talk about the latest news and goings-on.

In this short episode, I tell the tale of my registrar DNS name hosting for the last 25 years and what I prefer for a cheap and reliable name registrar.

Bret and Nirmal are joined by Chris Townsend, the engineering manager for Canonical's Multipass team, to discuss how to use Multipass as the easiest local virtual machine for Docker, Kubernetes and more!

Bret is joined by Demetrius Malbrough and Joseph D'angelo from Veritas, the company that makes NetBackup amongst many other data protection tools.NetBackup has been around at least 25 years and I've been using it over 20 years, although not recently. So we had the two gentlemen from Veritas on the show to break down the evolution of NetBackup to a Kubernetes native backup solution. We also talked about additional products that make sense in a backup context, like their InfoScale storage management solution, and we tried to break down some of the technicals. What are we talking about when we mean deploying NetBackup on Kubernetes?  How does InfoScale fit into that? And generally, just helping me catch up with the last few years as NetBackup 10.0 has been released. I asked lots of questions and we got some interesting questions from the audience.The Live recording of the complete show from October 19, 2023 is on YouTube (Ep. #238).★Topics★Veritas Kubernetes solutionsInfoScale Free Developer Edition60 day–trial of Veritas InfoScale for KubernetesCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Demetrius Malbrough - Guest Joseph D'Angelo - Guest You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!Grab the best coupons for my Docker and Kubernetes courses.Join my cloud native DevOps community on Discord.Grab some merch at Bret's Loot BoxHomepage bretfisher.com (00:00) - Intro (01:15) - Introducing the guests (03:38) - The Evolution of NetBackup (07:45) - The NetBackup Pitch (10:52) - How is NetBackup Deployed?

Bret and Nirmal are joined by Ken Collins, AWS Serverless Hero and Principal Engineer at Custom Ink to discuss all things Lambda and to dig into the details of running containers in serverless.

Bret and Nirmal are joined by Grayson Adkins and Josh Thurman on the show. They are co-founders of Uffizzi, an environments-as-a-service company for Docker Compose and Kubernetes.

Bret is joined by Dan Garfield of CodeFresh to talk about growth of GitOps as a standard, growth of Argo, and more.

In this episode, Bret and Nirmal talk with Brian Douglas of OpenSauced.

Bret and Nirmal welcome Idit Levine, Founder/CEO Solo.io. Idit focuses on Service Mesh, API-GW and Multi-Cloud networking, and security.Idit has been involved in the Containers/DevOps community for 10+ years, building products from Docker to Envoy to Kubernetes, and now Istio and Cilium. We talk about Istio, Ambient Mesh, Envoy, Zero-Trust Security, Cilium, eBPF, Multi-Cloud and more.This is not the first time we've talked about Solo or Service Mesh. Ambient Mesh is Solo's new product that simplifies the install and infrastructure costs of essentially running Istio. I'm really hopeful that this is going to help a lot more people implement Istio because traditionally, it does have a lot of parts and a lot of costs with the sidecar approach, but this new approach reduces the number of essentially proxies and parts that you're running on each node of your Kubernetes cluster.

Bret and Matt welcome special guest Brendan Burns, CVP Azure Cloud Native & Resource Management, and also a founding member of the Kubernetes project.Because Brendan is one of the three original co-founders of the Kubernetes project back in 2013 at Google, he's a little bit internet famous in open source and Cloud Native. So I was a little nervous going into this because I had so many questions. We took some live questions as we always do from YouTube live, and I thought it was a really great episode of a little mix of talking about Azure and some of the things you can do with containers, some of the things they're working on, some of the things that he's focused on that we haven't seen yet. We talk about AI and how that relates to some of these things. We even talk about WASM or WebAssembly, one of my favorite topics of the last year, because that's important so it was great to get his perspective. And I think my favorite part of the show is where we really talk about the next layers of abstraction, or maybe even the ways that we can deploy to Kubernetes or make it simpler to manage and deploy to. And that's been a real challenge for the community ever since Kubernetes was created in making it more accessible to more people, without it being so complex to manage and deal with underneath. And Brendan has some really great views on what it's going to take it to get us there.Live recording of the complete show from June 15, 2023 is on YouTube (Ep. #221).★Topics★Ways to run containers on AzureDaprWebAssembly on Azure KubernetesWasmtimeTwelve-Factor AppSupport this show and get exclusive benefits on Patreon, YouTube, or bretfisher.com!★Join my Community★Get on the waitlist for my next live course on CI automation and gitops deploymentsBest coupons for my Docker and Kubernetes coursesChat with us and fellow students on our Discord Server DevOps FansGrab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Brendan Burns - Guest (00:00) - Intro (03:10) - Introducing Brendan (08:47) - Advice for starting to run containers (30:30) - Reducing complexity with AI (34:41) - Addressing DevOps fatigue (42:38) - Running WebAssembly on Kubernetes (54:23) - LTS Linux Distributions (59:28) - What's next after containers and orchestration?

Bret and Matt welcome Michael Cade, the field CTO at Kasten by Veeam. If you've been around servers for a while, you probably have heard of Veeam. It made its debut back in the late 2000's when virtual machines and implementations of VMs were big. I first found out about them back in those days, because it was a great free product for small virtual machine environments and data centers. They've made tons of additional backup and recovery products over those years, and now they have Kasten K10, which is a Kubernetes backup and restore/recovery product. Michael discussed with us the origins of K10 and some of the major features. We get into some demos, which you can check out in the original YouTube live show.

Bret and Matt welcome Jake Warner back to the show to talk about LowOps. What does LowOps mean? What can Cycle offer us as an alternative to Swarm and Kubernetes?Jake Warner is the CEO and founder of Cycle.io. And I had him on the show a few years ago when I first heard about Cycle and I wanted to get an update on their platform offering. On this show we generally talk about Docker and Kubernetes but I'm also interested in any container tooling that can help us deploy and manage container based applications. Cycles' platform is an alternative container orchestrator as a service. In fact, they go beyond what you would provide normally with a container orchestrator and they provide OS updates, networking, the container runtime, and the orchestrator all in a single offering as a way to reduce the complexity that we're typically faced with when we're deploying Kubernetes. While I'm a fan of Docker swarm due to its simplicity, it still requires you to manage the OS underneath, to configure networking sometimes, and the feature releases have slowed down in recent years. But I still have a soft spot for those solutions that are removing the grunt work of OS and update management and helping smaller teams get more work done. I think Cycle has the potential to do that for a lot of teams that aren't all in on the Kubernetes way, but still value the container abstraction as the way to deploy software to servers.Live recording of the complete show from May 18, 2023 is on YouTube (Ep. #217).

Bret and Matt are joined by Corey Quinn to talk about AWS and containers.Corey Quinn is the Chief Cloud Economist at the Duckbill Group. You may have seen or heard some of his in-depth AWS content, including his Last Week in AWS newsletter and blog, Corey's podcast Screaming in the Cloud and the AWS Morning Brief, or his highly produced YouTube videos on the Last Week in AWS channel. Corey runs the Duckbill Group, a company of people focused on helping clients understand and manage their cloud spend. If I had to describe Corey in a sentence, he's a quick thinking AWS expert who is one part cloud strategist, and one part sarcasm. The inspiration for this show came from his blog series, focused on all the ways to run containers on AWS, which is to say there's a lot. Dozens of ways, in fact, which I took as a testament to how containers have won the cloud as the primary way to package and deploy software to servers. Now, the hard part for us is to figure out which method we're going to choose for running those containers. We go on lots of tangents, but overall it was a fun conversation and I hope you enjoy this episode.Live recording of the complete show from May 4, 2023 is on YouTube (Ep. #214).★Topics★The Cloud Resume ChallengeLast Week in AWS17 ways to run containers on AWS17 MORE ways to run containers on AWSSupport this show and get exclusive benefits on Patreon, YouTube, or bretfisher.com!★Join my Community★New live course on CI automation and gitops deploymentsBest coupons for my Docker and Kubernetes coursesChat with us and fellow students on our Discord Server DevOps FansGrab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Corey Quinn - Guest (00:00) - Intro (07:19) - 17 Ways to Run Containers on AWS (09:57) - If you're using the cloud, use the cloud!

Bret and Matt are joined by Brent Baude and Dan Walsh from Red Hat to talk about the latest with Podman, Quadlet, Podman Desktop and Podman machine, and how it all works with Kubernetes.-------------------------------------★ Enroll now for my next Live course, GitHub Actions + Argo CD, scheduled for July 10-21. Go to bret.courses/autodeploy to sign up. ★------------------------------------Dan Walsh, a Senior Distinguished Engineer at Red Hat, has been working with containers since the beginning. He's a contributor to Docker, Project Atomic, SELinux, and a lot more. He literally wrote the book on Podman. Brent Baude, is a Senior Principal Software Engineer at Red Hat and an architect and a primary maintainer of Podman, and contributes to many of its associated technologies like CRI-O, Buildah, and Skopeo. We go through a lot of tooling in this episode because Red Hat has taken a different stance than Docker in how it delivers its container tooling. You might say they take the approach of the Unix philosophy of every program does one thing well. Most of us know Docker and how it bundles many things related to containers into a single command line and daemon, yet some would prefer to isolate pieces of container management functionality into discreet, smaller programs - one for building images, one for running containers, one for communicating with registries, one for adding a GUI to your container manager, and one for managing the container VM. It's just sort of how I would break down the Podman ecosystem.And while that may seem like a lot of things, it's basically what Docker does for you in a single tool, yet the isolation of these tools is what can make them purpose-fit when you only need a fraction of the functionality of Docker. For example, one of Podman's core tenants is that it tells systemd to run your pods, which is the initialization process on most Linux distributions. In this way, your containers become more like standard system processes, rather than the Docker way of running all containers under the Docker Daemon process itself. Now many of us have heard of the other two original Red Hat container projects, Skopeo and Buildah, but there's now an increasing number of things the Podman ecosystem can do. So I'm grateful to Dan and Brent for coming on to break down the new parts of this toolkit and how we might use them.Live recording of the complete show from April 20, 2023 is on YouTube (Ep. #212).★Topics★Podman WebsitePodman Desktop WebsiteDan Walsh's book, Podman in ActionPodman Machine referenceQuadlet Blog PostPodman and Quadlet Blog PostSupport this show and get exclusive benefits on Patreon, YouTube, or bretfisher.com!★Join my Community★New live course on CI automation and gitops deploymentsBest coupons for my Docker and Kubernetes coursesChat with us and fellow students on our Discord Server DevOps FansGrab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Brent Baude - Guest Dan Walsh - Guest (00:00) - Intro (06:20) - Dan's history with containers (12:46) - The recommended way to get Podman (13:49) - Podman Machine (15:21) - How is Podman Machine installed (18:37) - How is Podman organised (21:16) - Podman Compose explained (27:15) - Podman Desktop (30:46) - Podman and Docker extensions (32:10) - Support for Kubernetes YAML (38:48) - Podman and systemd workloads (44:38) - How to get started with Podman (53:32) - Overlaying networks with Podman

Bret and his co-host, Matt, are joined by Jason Dellaluce and Luca Guerra from Sysdig to talk about Falco, a tool I recommend for production clusters and knowing about any bad behavior on your servers. -------------------------------------★ Enroll now for my next Live course, GitHub Actions + Argo CD, scheduled for July 10-21. Go to bret.courses/autodeploy to sign up. ★------------------------------------Falco is a security tool I've mentioned multiple times on this show, because I mostly think that a low level security focused logging product is something that every production server needs. The ability to log unexpected events and behaviors on your Linux host is powerful and necessary to be able to audit what's really happening on your infrastructure outside of your app itself. Falco has been a CNCF incubating project for over four years, and I was immediately drawn to it in its early days, because it was container and Kubernetes aware and it could log and alert with default rules for everything, from someone starting a shell inside a container, to a bash history file being deleted, to a container trying to talk to the Kubernetes API. This episode will be useful for those of you new to tools like Falco and for those familiar with its basics, but also wanting to learn about newer features and use cases, which I did some learning on myself in this episode.Live recording of the complete show from April 6, 2023 is on YouTube (Ep. #210).★Topics★Falco websiteFalco on CNCFSupport this show and get exclusive benefits on Patreon, YouTube, or bretfisher.com!★Join my Community★New live course on CI automation and gitops deploymentsBest coupons for my Docker and Kubernetes coursesChat with us and fellow students on our Discord Server DevOps FansGrab some merch at Bret's Loot BoxHomepage bretfisher.comCreators & Guests Bret Fisher - Host Cristi Cotovan - Editor Beth Fisher - Producer Matt Williams - Host Jason Dellaluce - Guest Luca Guerra - Guest (00:00) - Intro (04:18) - Introducing the guests (07:19) - What is Falco?

Bret is joined by Lukas Gentele and Rich Burroughs from Loft Labs to look at a new project called DevPod, that supports dev containers and VMs. It works with local Docker instances and AWS, GCP, Azure, and several other cloud providers. The project is compatible with Microsoft's DevContainer standard, which means it works with the VC Code standalone app and VS Code in the browser.-------------------------------------★ Enroll now for my next Live course, GitHub Actions + Argo CD, scheduled for July 10-21.

In this episode, we announce the release of DevPod and also go through some demos. I'm already thinking of how I might use it in my own developer workflow.Live recording of the complete show from May 16, 2023 is on YouTube (Ep. #216).
